How do you even go about making sure the bells are secured in that case? Jeez. What a task.
Correct, but on the other hand, assuming that it was an accident is speculation as well. The reports from the scene saying accident seem premature, but they do lend more credence to the accident angle. I think it's wrong to say "because of what has happened lately, this is intentional" but it does demand consideration for sure.
Essentially, it's too early to say for sure either way.
